Making rice vinegar and dandelion vinegar
We can't always rely upon apples and grapes to make vinegar, because most likely as their seasons come and go, we didn't make enough. It was a common complaint because vinegar was so useful for so many things that people on the frontier ended up using it up. “Heck! I need some, what to do?”
Well the easier thing is to make rice vinegar. No doubt you bought tons of it, because it's cheap and most people will be eating a lot of rice and beans. Here's a recipe for making it using only water, rice, yeast, sugar. Remember, you can find sugar in diverse places. You can get the yeast to naturally collect in time as well. See previous postings.

Many kinds of your culinary herbs will also flavor your vinegar. Make more than you think you'll need and flavoring some means you'll be more likely to use that for cooking and the other for other uses.
